There’s no making sense of violence that takes the life of a little girl, even when police offer an explanation.

Nylah Irene Franco-Torrez, 3, died after she was shot in the head as she played outside a San Bernardino home Monday evening. Another 3-year-old girl and her pregnant mother were wounded in the shooting; they remained hospitalized late Wednesday.

San Bernardino police have pledged a “relentless” pursuit of the shooter, who some witnesses say opened fire on the D Street home as he and others rode past on bicycles.

Police say the shooting may have been an act of retaliation, an explanation that fails to help us understand any better why a 3-year-old girl has been slain. Whatever did she – or the other victims, for that matter – do to deserve such a heartless attack?

The horrific shooting, sadly, was not the only violence that rattled San Bernardino’s streets that day. In a 12-hour span, police responded to three other unrelated shootings, one of which may take the life of a man who remained in critical condition Wednesday at a local hospital.

Nylah’s death was the first homicide in San Bernardino in 61 days, a tragic end to what had been a relatively quiet summer. Her death is an important reminder that violence in our city’s streets does not discriminate against the very young.

We remember Mynisha Crenshaw, an 11-year-old girl who was caught in the cross hairs of a gang shooting in November 2005; and Anthony Ramirez, also 11, killed in 2006 as he played basketball with his brother and friends.

Our sympathies remain with the families and friends who continue to grieve for Mynisha, Anthony and now Nylah.

To anyone tempted to throw up their hands, say there’s nothing we can do: We can do something. We can remember these children and look out for others like them. We can hold those who hurt them accountable.

And to those who know anything – anything at all about Nylah’s death or the person responsible for it or any other shooting – we ask you to come forward.
